Radiation Units,sorbing medium. The source of nuclear radiation may be radioactive atoms or equipment such as X-ray machines. The effect of absorbing the more familiar types of radiation, such as heat, is to raise the temperature of the absorbing medium. If this medium is the human body, or part of it, the rise in横截,横断 发表于 2025-3-29 13:32:11
Biological Effects of Radiation,active substances, leads to biological effects which may later show up as clinical symptoms. The nature and severity of these symptoms and the time at which they appear depend on the amount of radiation absorbed and the rate at which it is received. Radiation injuries can be divided into two classesabysmal 发表于 2025-3-29 16:28:50

Radioactive Waste,roblem. It has been estimated that the total quantity of radioactivity in use in research and medicine in 1938 was less than 30 TBq, corresponding to about 1 kg of radium derived from natural sources. Today, a single large power generating reactor may contain in excess of 10. TBq of fission productsCoeval 发表于 2025-3-29 23:54:23
